The Physical Activity and Health of Specialists Working with Computers
Bibliographic record
Abstract
The survey on physical activity and health of specialists working with computers was accomplished in Lithuania in 2011. In the survey participated 204 specialists working with computers at the offices, at small and medium sized business companies. Chi-square test was used and the significance level p ≤0.05 was considered statistically significant. The study revealed as about one-third (37.3 %) specialists working with computers everyday feel tired after work, and one-third (34.3 %) after work feel tired 2 - 3 times per week. About half (52%) of specialists working with computers 5-10 hours per day work in sitting position, 35 % work in sitting position 1-5 hours per day, and 11 % work in sitting position more than 10 hours per day. No significant differences between men and women were observed. A half (51%) of specialists working with computers stated as their physical health is good, 34 % - as medium, 11% - as very good. More men than women stated as they have good health (p=0.027). One-third (33%) of specialists working with computers have health problems. Men less than women complain on health problems (p=0.003). The physical activity of working with computers is too low. Both men and women need more attention to the physical activities. The quarter (24%) respondents are taking exercise or go in for sport at least 30 min. per day once per week, 22 % -2-3 per week, 22% -2-3 times per month, 20 % - few times per year or less. Every day at least 0.5 hour per day for physical activity use only 12% respondents. About half of working with computers (58%) agrees, as they should be more physical active. One-third (33%) think, as they have enough knowledge on importance of physical activity to the health, one-third (31%) think as they do not have enough knowledge. When working with computers mostly suffer back, shoulders and neck of the body. Little less, suffer sciatic and lumbar part of the body. Article in Lithuanian doi:10.5200/sm-hs.2012.077

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
